I feel your pain now it's just sans with a flaming eye (cuz originality is too hard) or being sad
mettaton in his final form because the original form doesn't exist anymore for some reason and bait for sexual orientation and gender discussions
asgore and so sorry being the spawn from hell for some reason
alphys just being a walking anime joke
papyrus just a defenseless baby when he could be even stronger than sans
and it goes on and on
the only 2 characters i don't see being ruined are just napsta and muffet
